A horribly mutated alien arachnid is growing at an exponential rate and heading toward downtown Los Angeles. The military seems powerless to stop it. But a cocky local exterminator (played by Greg Grunberg of "Heroes" and "Alias") thinks he's got the skills to stop this 10-story monster. The title alone should give you a good indication of this horror-comedy's B-movie-loving tone. 90 minutes PG-13.
